    No internet can be solver real quick. A suitable battery with a DC plug directly into the router DC socket solves that problem. That is what I use and an alarm/gate motor battery lasts 5 hours and not even very flat yet. Even some china mall Li-Ion as used in laptop batteries can do the trick for the 2-3 hours.
    The device Richard posted is also a great item to have in these times.

    Edit - Note to self. I really must get around to installing that buzzer and indicator light in my DB so I know what is feeding my house power.
    A belated reply...

    I am sure you know precisely what is powering your house at any given time...

    Actually no. I know itís electricity. But where it is comming from, not so much.

    I have to put down my beer and put the DSTV on Statue and take a walk to the garage and have a look in the DB to see.

    Eskom did a scheduled connection yesterday, giving us bout 16 hr warning. the off should have been 8 hrs , but it is still ongoing, at 25 hrs now.
    I have a 700 KVA running the packhouse, 85 % of the power is for the coldrooms.
    But the water is running out and to start up the Pumps I need 4 MVA
    I am dribling in a bit of water with my 20 000L tanker, but it will not keep up with the demand.


    At home like I posted above, the small petrol Genny is just keeping the fridge and freezer cold, and charging a few Phones on the side.

    Is the 700kVA temporary power provided by Eskom?

    This is when the lack of power is very Very bad. How much diesel does such a genset use per hour?

    Gotta love the smell of diesel in the air with about 5x noisy monster generators screaming at a gazillion decibel's while at the office..

    ..and another is the outage of traffic lights on the commute home with all those 'tail gunners' trying their utmost to create insurance claim opportunities..

    Once home it is bliss and have backup for Eksdom if needed, before the solar & batteries the main issue was "no power" = "no water", but my 5kva MicroCare is taking 'care' of that now

    Strangely enough, I have found traffic lights without power MUCH safer and more efficient than normal. (Up until a very high traffic density)

    Mine runs at about 100L /hr at full tilt, current usage is about 90-95L / hr.

    Very interesting. A 700W genny can use 1L/h and yours produces 1000 times more power and uses 100 times more diesel. Thus consumption is 10 times better.

    TEEN die Oranje rivier ....

    Irrigation farming. And it is now harvesting season so the chiller plants are RUNNING ... the absolute WORST time for these farmers to have load shedding !!


    Not sure how bad this is for the "date" farmers, but I know the table-grape farmers MUST keep the "cold-chain" or their clients rejects the shipment ....




    We work with Klein Pella's neighbours, so I get to see the equipment and what their requirements are .....

    By the by I notice Bidvest Terminals are busy with a massive (4No. x 16m diam x 60m long bullets) LPG storage installation in RB; going to be coming in useful methinks - er, unless Eskom want it for their peaking generator a bit south of RB.

    To solve all the problems, I just went the Generator route. I have two tenants living on my property, so it is also about safety, not only convenience. I would eventually maybe want to go solar permanently on certain circuits in the house, at least ALL of the light circuits and the plug circuits in the bedrooms and living rooms, I think that 4 100 ah batteries and 3 or 4 x 330w PV panels and possibly a 1kw inverter. I need to investigate a bit more. Maybe I must go and visit Johann Maree on his plot in Benoni to learn a bit more about PVs and batteries....

    My suggestion with a Generator for household use: Get at least a 7.5 Kva unit. It can support most household items except the electric stove in the one flat and geyser. I can even weld with my ancient oil-filled welder when its is load shedding time. I have the main house 2 cottages. Run it max for two hours during the day and not later than 22h00 at night. The only issue I have with that is the security lights for the rest of the night. Three gates and 2 garage doors use 12v battery motors.

    I bought one of those Chinese Honda copies (Paid R9,950 in 2014) and have been using it now for the past four years without an issue. I always refill the tank (25lt) and 20lt Jerry Can after running it for more than 3 hours at night. My tenants and the family know, if the power is out, the genny runs to 21h30, at the latest to 22h00. I seldom run it for more than 1 hour at a time during daylight hours. It uses between 4 an 6 lt in a 3 to 4 hr period, depending on the load.

    I have built a fairly soundproof room away from the house next to the lapa, with the exhaust (35mm pipe) going up through the roof. It does have two silicone pipe joints in it to take up the play between the vibrating genny and the solid brackets going through the roof.

    On the main DB, the cable from the genny goes into a 3 position rotary switch with "Mains", "Off" and "Gen" settings. I also have an audible alarm with a flashing light that is connected to mains. This is turned on when the mains are off, so when mains do return, the light flashes and the buzzer makes a racket, so we know we can switch off the genny.

    I have a 6mm cable from the genny to the main House DB and that then also feeds the 4 sub DBs that are fed from there (as per normal from the main house DB). I have the main house, 2 cottages 3 garages/workshop areas and a lapa. We have a total of 5 fridges and luckily gas stoves, gas geyser for the house and a solar geyser for the outbuildings.

    I also run the solar geyser on mains on a timer from 22h00 for one hour and again from 04h00 to 05h30 daily. In winter it does cool down substantially at night, and of course in summer we do have those rainy days when we just need to give it that extra little "bump-up". I do however turn the geyser's mains switch off in case it does switch on while the genny is running, as I know the geyser will overload the genny

    The switch-over form mains to genny has to be done manually, the automated system is just too darned expensive. The genny does however have a manually activated electric starter and its own starting battery.

    I did it all myself, with the exception of the rotary switch, which I got a sparky to do for me, in order that I could obtain a Certificate Of Compliance (mostly for insurance purposes).
